Rust not launching from Steam

I have been trying to launch Rust from Steam for the past 5 months with no luck. As soon as I click play it instantly displays a message, Rust.exe has stopped working, then closes a second later. It launches from C:\Program Files (x86)\Steam\steamapps\common\Rust , but displays the message EAC: User Disconnected when trying to join servers.

I have reinstalled Rust 8 times
I have verified integrity of game cache
I have reinstalled Steam
I have run Steam and Rust as administrator
Run compatibility troubleshooter
Reinstalled EAC
Updated .Net Framework
Updated Rust and changed beta groups and updated once again
Used launch options such as -force-d3d11

I am currently on Windows 8.1
GPU: Nvidia Gtx 750
CPU: Intel Core i5-4460 @ 3.2GHz
RAM: 8 Gb

I have played Rust many times in the past. I was able to play for the past month or so by launching through C:\Program Files (x86)\Steam\steamapps\common\Rust by playing on one server that didn’t display EAC: User Disconnected, when joining it. Recently the server reset and after restarting I was unable to join it as it also displayed EAC: User Disconnected.

I have read of many people with this issue but no one has found an actual fix.

If you know of a fix please let me know. I am beyond desperate and miss Rust as it is my favourite game.

Solution !
Fixed it by upgrading to Windows 10 :smiley:
